The TA903 consists of two Wheatstone bridges at an angle of 90° to each other. A rotating magnetic field at the sensor level supplies two sine signals with a phase shift of 90° relative to each other with a simple frequency of the magnetic field. As such, the signal information is clear across a 360° rotation of the magnetic field.
The TA903 features PerfectWave technology and delivers extremely low harmonic output signals.
Sensitec is increasing the sensor efficiency by means of various design modifications to the chip layout. The patented solutions, described more closely below, also contribute to better signal quality, reduced sensitivity to stray fields and increased control accuracy.
